Appendix

The is the part of the large intestine that moves upward from the cecum along the right side of the abdominal cavity.

Ascending colon

The is the part of the large intestine that runs horizontally across the abdomen, connecting the ascending colon to the descending colon.

Transverse colon

The is the part of the large intestine that moves downward along the left side of the abdominal cavity, connecting the transverse colon to the sigmoid colon.

Descending colon

The is the part of the large intestine that connects to the rectum and is shaped like an 'S.'

Sigmoid colon

The is the opening at the end of the digestive tract through which waste is expelled from the body.

Anus

The is an organ located in the upper right abdomen that produces bile, processes nutrients from the blood, and plays a key role in metabolism and detoxification.

Liver

The is the larger portion of the liver located on the right side of the body, playing a key role in metabolism, detoxification, and the production of bile.

Right lobe of liver

The is the smaller portion of the liver located on the left side of the body, involved in various metabolic processes and the production of bile.

Left lobe of liver

The is a lobe of the liver located on its posterior side, playing a role in metabolic processes.
